  1. Moving into November and it is time to open another thread to discuss the upcoming Winter Sports Season in the Northern Hemisphere. The Net Weather Ski Centre is here -> https://www.netweather.tv/weather-forecasts/travel/ski This contains a massive range of Skiing related content. Blogs - This will contain forecast blogs for this coming season, the Alps blogs will start early December to co-incide with the majority of resorts opening (hopefully). Paul will also be adding a number of blogs over the course of the season, which will also cover conditions over the the USA and Canada. Resort Weather Forecasts - Resort Weather forecasts based on GFS, updated 4 times a day, together with current conditions. Wengen Forecast and Conditions Destination Guides - We have a number of destination guides, and we are aiming to extend this over the coming season, so if you would like to contribute or would like your resort featured, please let us know. Scotland Section - There is also a section dedicated to the conditions over Scotland. https://www.netweather.tv/weather-forecasts/travel/scotland-ski This thread will now run throughout the 2017/18 season, so please give your thoughts for the season ahead, and new features you would like to see. A few thoughts :- Will the winter season start on time this year or will we have to wait until post Christmas for proper low level snow. Will the USA/Canada continue to have the best of the conditions. Will the East West Alps split be an issue again this year. How important are snow cannons to the ongoing viability of ski season. Any winter topic of your choosing. Over the course of the season keep bringing those Alpine related stories, whether from local papers or your skiing trips, which made this thread such a joy last year.
  2. Synoptic Summary and Current Conditions We are moving into the final parts of the skiing season, with many lower resorts starting to close down for the year and there were some very warm temperatures last week. However there is still some good skiing conditions on upper slopes, with decent snow totals from heavy snowfalls past the New Year and a top up in some resorts in recent days. The weather pattern for the weekend sees low pressure to the South East of the Alps, with South Westerly winds over the Alps. During the course of next week, the pressure slowly builds to the South East of the Alps, however winds generally from the South West, and turning milder towards the end of next week. Alps Detail Saturday - Winds from the South West, coldest to the North and West, Mildest South and East 850Hpa temps +0c to +3c (French Alps, N Switzerland, N Austria, S Germany and Liechtenstein) FL 1400m to 2000m 850Hpa temps +4c to +7c (S Switzerland, Central and Southern Austria, Italy) FL 1800m to 2400m Sunday - Winds from the South East, coldest to the North and West, Mildest South and West 850Hpa temps +2c to +4c (French Alps, N Switzerland, N Austria, S Germany) FL 1800m to 2000m 850Hpa temps +4c to +7c (Switzerland, Central and Southern Austria, Italy and Liechtenstein) FL 2000m to 2500m Monday - Winds from the South West, milder generally 850Hpa temps +7c to +13c (generally) FL 2200m to 2600m (West) 2400m to 3400m (East) Tuesday - Winds from the South West, milder generally 850Hpa temps +7c to +11c (generally) FL 2200m to 2600m (generally) Wednesday – Winds generally from the West to North west, colder for a time in the West 850Hpa temps +3c to +7c and FL 2000m to 2400m (West) 850Hpa temps +8c to +13c and FL 2600m to 3200m (rest of Switzerland, Northern Italy and S Austria) Thursday - Winds from the South West, milder generally 850Hpa temps +7c to +13c (generally) FL 2200m to 2800m (generally) Friday – Winds from the South West, even milder 850Hpa temps +9c to +14c (generally) FL 2900m to 3200m (West) 3200m to 3500m (East) Precipitation Saturday looks rather unsettled with some heavy showers, more especially for southern parts of the Alps. Snow generally above 2000m. Drier Sunday before more showers edge from the west Monday afternoon, lasting well in the evening. Snow generally above 2200m. Tuesday again drier, before an area of low pressure is set to move North Eastwards across the Alps during Wednesday, perhaps 20cm of snow possible above 2000-2200m. Looking largely dry for the rest of the week. Summary and Outlook Spring conditions set to continue this week, However with some snow possible of the higher slopes, generally above 2000-2200m. Quite mild at times, but generally not excessively mild for April, however possibly turning very mild just before next weekend.
  3. Synoptic Summary and Current Conditions Snow conditions are starting to reflect that we are now in April, with spring snow conditions becoming more widespread, however good skiing conditions remain on the higher slopes (as ever). Charts – Weekend High Pressure starting to build over Eastern Europe, with winds from a South to South Easterly direction bringing some very warm air up from Northern Africa. With general low pressure, some moderate precipitation, mostly rain is possible. Charts – Monday and Tuesday Staying mild or very mild for the start of the next week and remaining unsettled with further moderate precipitation likely. Charts – Wednesday to Friday Turning much colder from the West to North West, with a Polar Maritime airflow developing, remaining unsettled with a greater chance of snow. Alps Detail Saturday – Very mild winds from the South to South East 850Hpa temps +8c to +13c (generally) +2c to +5c (Eastern Austria) FL 2800m to 3400m (across the Alps) Sunday - Very mild winds from the South to South West 850Hpa temps +8c to +14c (generally) FL 2500m to 3000m (South and Western Alps) and 3200m to 3500m (Germany and Austria) Monday - Winds generally from the West to South West 850Hpa temps +5c to +13c (generally) FL 2400m to 3000m (generally) Tuesday - Winds generally from the West to South West, slightly cooler from the west 850Hpa temps +6c to +12c and FL 2400m to 2700m (SW Germany, Switzerland, France, NW Italy) 850Hpa temps +10c to +13c and FL 2600m to 3200m (SE Germany, Austria, NE Italy, Liechtenstein) Wednesday – Winds generally from the North East, colder again from the North West 850Hpa temps +1c to +4c and FL 1600m to 2000m (French Alps, N Switzerland, Germany, N Austria) 850Hpa temps +4c to +12c and FL 2000m to 2800m (rest of Switzerland, Northern Italy and S Austria) Thursday – Winds generally from the North East, colder again from the North West 850Hpa temps -3c to +1c and FL 1000m to 1600m (West French Alps, N Switzerland, Germany, Far N Austria) 850Hpa temps +2c to +9c and FL 1600m to 2400m (East French Alps, rest of Switzerland and Austria, Northern Italy and S Austria) Friday – Winds generally from the North East 850Hpa temps -1c to +1c and FL 1000m to 1600m (Generally) 850Hpa temps +1c to +4c and FL 1400m to 1800m (S Switzerland, NW Italy, SW Austria) Precipitation Weekend - Dry for the east of the Alps over the weekend, with some showers in the far South West on the Alps on East on Saturday. The showers developing a bit more widespread in the west later on Sunday, Snow above 2500m or so. Monday - Tuesday - Staying dry over the East of the Alps, further showers or longer periods of precipitation for the Western Alps at times, Snow again limited to above 2500m. Wednesday - Friday - Fronts edging in from the North West and crossing the Alps towards the end of week, on Wednesday snow about 2000m. However for Thursday and Friday, snow levels closer to 1000m-1200m with the chance of appreciable snow totals. Outlook - For the weekend and the start the next week, some very mild weather with some heavy rain likely in western Alps and some very warm sunshine for the Eastern Alps, sunscreen is a must. This is likely to severely impact the slopes especially lower down, however towards the end of the week, turning colder again with some fresh slopes down to medium slopes.
  4. Synoptic Summary and Current Conditions Snow conditions remain generally good or very good across the Alps. Snow over Austria in recent days has improved the conditions here. Elsewhere there has been a lack of snow generally for the past week and on piste the conditions remain very good. However off piste conditions are worsening and some fresh powder is desired. With temperatures dropping over recent days, spring snow has also been less of a problem. Charts - Saturday to Monday For the weekend, low pressure moving the over the UK and into North Western Europe will try to edge South Westerly winds and unsettled weather over the Alps. For Saturday, it should remain mostly settled over the Alps as High Pressure hangs on. For Sunday and into next week, the fronts start to edge in over the Alps form the North West, bringing some moderate precipitation along with fluctuating temperatures. Charts – Tuesday and Wednesday By midweek, the flow turns more to a westerly with further mostly showery precipitation with 850Hpa temps generally above freezing, the precipitation concentrated in Northern and Western areas. Charts – Thursday and Friday Towards the weekend low pressure to the south may introduce southerly winds with the risk of some very mild air, but this is a long way away at present. Alps Detail Saturday – Winds from the South to South West, Turning milder from the West 850Hpa temps +2c to +8c and FL 1800m to 2400m (France, Switzerland, Northern Italy, Liechtenstein, SW Germany, Western Austria) 850Hpa temps -1c to +2c and FL 1400m to 1800m (SE Germany, Northern and Eastern Austria) Sunday - Winds generally from the South to South West, Turning colder from the North West 850Hpa temps -1c to +2c and FL 1400m to 1800m (W France Alps, N and W Switzerland, Liechtenstein, SW Germany) 850Hpa temps +1c to +5c and FL 1800m to 2400m (Austria, S and E Switzerland, Northern Italy, E France Alps) Monday - Winds generally from the West to South West 850Hpa temps +3c to +7c and FL 1900m to 2200m (generally) 850Hpa temps +1c to +3c and FL 1700m to 1900m (Far SE areas - SE Austria, NE Italy, and Far NW areas, NW Switzerland, Far SW Germany) Tuesday - Winds generally from the West, Low Pressure over the South of the Alps and milder here 850Hpa temps 0c to +2c and FL 1400m to 1800m (Southern Germany, N Switzerland, Liechtenstein, N and E Austria) 850Hpa temps +2c to +6c and FL 1800m to 2200m (S and W Austria, S Switzerland, Italy, France Alps) Wednesday – Winds generally from the West to South West, as Low peruse moves east over north pars of the Alps. 850Hpa temps 0c to +3c and FL 1400m to 2000m (N and W Switzerland, SW Germany) 850Hpa temps +4c to +8c and FL 2200m to 2600m (French Alps, rest of Switzerland,. SE Germany, Northern Italy and FL 2600m to 3000m ( Far east Austria) Thursday – Low Pressure over the Alps, much milder from the South 850Hpa temps +4c to +8c and FL 2400m to 2800m (generally) Friday – Huge uncertainty with GFS model runs varying 850HPa temps by as much as 15c for some parts of Austria, however more consistently showing looking milder weather to the south. Precipitation – A succession of fronts are set to move in this week from the west, most are cold fronts, with snow to quite low levels at times, especially to start the week. Weekend - Precipitation for Austria is expected to continue through Saturday morning, before decaying slowly during the afternoon, snow initially above 1000m, perhaps 1200m later. A cold front from the North West slowly edging east during Sunday, reaching central areas overnight before decaying in Austria Monday, Snow generally 1200-1400m on the front, but higher on the front edge of the front and over Italy, 1600-1800m here. Monday - Early Next Week Later on Monday, the next front edges in from the west for Western parts of the Alps, with snow restricted above 1600m-1800m for daytime and evening. However as colder air pushes in from the west, snow levels falling back to around 1200-1400m overnight and into the morning, with a few more hours of precipitation for western areas, before it moves to Austria by early morning. Showers for Tuesday afternoon over Southern parts of the Alps with snow levels back up to close to 1800-2000m.Further showers seem likely on Wednesday, with snow above 2000m, there is a chance of frontal precipitation from the NW later with snow to 1400-1600m, but uncertainty as to its location. In terms of snow amounts, 25-50cm of snow are possible in places, above 1750-2000m, below 1500m though and the snow/rain mix is always likely to change. Outlook - So in summary a messy week, conditions look pretty good for Easter Weekend, with generally good snow conditions. For the first part of next week, a succession of fronts from the west will bring precipitation with snow likely above 1750-2000m and to lower levels at times. Towards the weekend, perhaps turning very much milder from the south, but a lot of uncertainty.
  5. Synoptic Summary and Current Conditions There is currently an elongated High Pressure covering a narrow strip from Scandinavia running through the UK down to the Azores, with the Alps on the SE side of the High with cold/cool NE winds. Lower pressure to the South of the Alps over parts of Italy. Conditions over the Alps are very good generally with the recent heavy snowfalls over the past month, looking a bit drier for the coming week, with more in the way of sunshine, but some showers still possible at times more especially towards the South and South East of the Alps. Charts - Saturday to Tuesday For the weekend, the high pressure is set to move a little to be centred over Southern Scandinavia/ NW Midland Europe, before moving further north to be centred over northern UK through to Scandinavia by Tuedays, The flow is generally set to be from the East for the Alps. Lower pressure never to far away from the south, and some showers are likely to build up from time to time especially in the afternoon and for more Southern parts of the Alps. Charts - Wednesday to Friday A similar there towards the end of the week, perhaps with the pattern becoming a little more unsettled from the south, with a little more in the way of showers towards Friday. Alps Detail Winds generally from an Easterly direction, with the coolest weather on the whole for N and E Austria, S Germany and N/NW Switzerland, milder further SW for SW Switzerland, NW Italy, and Eastern French Alps) Saturday – 850Hpa temps -4c to -2c and FL 1000m to 1400m (Southern Germany, N Austria, N Switzerland, Liechtenstein, W France Alps) 850Hpa temps -2c to +3c and FL 1600m to 2000m (S Austria, S Switzerland, Italy, E France Alps) Sunday - 850Hpa temps -4c to -2c and FL 1000m to 1400m (Southern Germany, N and E Austria, N Switzerland, Liechtenstein, W France Alps) 850Hpa temps -2c to +3c and FL 1600m to 2000m (SW Austria, S Switzerland, Italy, E France Alps) Monday– 850Hpa temps -7c to -5c and FL 800m to 1000m (NE Austria) 850Hpa temps -6c to -2c and FL 900 to 1400m (S Germany, Liechtenstein, N Switzerland, C Austria, W France Alps) 850Hpa temps -2c to +3c and FL 1600m to 2000m (SW Austria, S Switzerland, Italy, E France Alps) Tuesday– 850Hpa temps -7c to -4c and FL 800m to 1100m (E Austria, S Germany, N Switzerland) 850Hpa temps -3c to +1c and FL 1200m to 1700m (W Austria, S Switzerland, Liechtenstein, Italy, France Alps) Wednesday – 850Hpa temps -6c to -2c and FL 800m to 1000m (E Austria, NW Switzerland, S Germany) 850Hpa temps -3c to +1c and FL 1100m to 1600m (W Austria, rest Switzerland, Liechtenstein, Italy, France Alps) Thursday - 850Hpa temps -3c to 0c and FL 1000m to 1400m (Southern Germany, N and E Austria, N Switzerland, Liechtenstein, W France Alps) 850Hpa temps -1c to +3c and FL 1400m to 2000m (SW Austria, S Switzerland, Italy, E France Alps) Friday – 850Hpa temps -5c to -2c and FL 900m to 1200m (N and E Austria, NW Switzerland, S Germany) 850Hpa temps -2c to +2c and FL 1400m to 1900m (SW Austria, S Switzerland, Italy, E France Alps) Precipitation A drier week than recently, however some showers are likely to develop at times, these most likely for Southern and Southern Eastern areas, and many of these may develop for the afternoon, after a dry sunny morning. The showers are not likely to be focussed on certain areas as per the precipitation charts, but they may well be isolated and heavy in nature, Weekend Showers tending to develop into the afternoon on both days, more especially for Austria, snow levels 1200m midday, down by 500m, by evening. Next Week Drier Monday perhaps more general precipitation for Western areas Tuesday into Wednesday, with afternoon showers again developing further east, snow level 1200m midday, dropping back to 500m or so evening/overnight. Showery precipitation again developing for Southern areas Thursday and Friday, some of the showers heavy and prolonged, snow levels upto 1500m midday, dropping rapidly back to 500m for evening/overnight. Snow Amounts Some topups can be expected, but less than recently generally, perhaps 25-50cm possible in some parts of Austria. Summary A drier and sunnier week over the Alps, but recent heavy snow should mean good conditions. The overnight very low temperatures and spring sunshine , should mean freeze thaw conditions, so a little icy for the morning and slushy for the afternoon, however better conditions expected on the higher slopes, say above 1500m. But overall a good week to go skiing, but take your sun cream.
  6. Synoptic Summary and Current Conditions The clock has ticked on and all of a sudden, we have moved into Spring, and you would think that things may start warming up. However the weather has not been that mild, whit plenty of snow above 1500m, while at lower resorts there has rain one day, and snow the next. However colder in recent days, with more general snow to lower levels. Currently there a is a cool NW flow over the Alps, with low pressure to the north of the Alps. Charts - Saturday to Tuesday A NW flow seems likely over the weekend, but switching round to an Easterly by Monday and generally unsettled for the most part with low pressure centred over Italy. Charts - Wednesday to Friday Unsettled with easterly winds to start, but High Pressure ridging up from the South West turning things much milder by Friday. Alps Detail Saturday – Turning colder from the North West, mild to start in Austria 850Hpa temps -3c to +2c and FL 800m to 1400m (France, Switzerland, SW Germany and Italy) (temps higher in the South) 850Hpa temps +1c to +4c and FL 1400m to 2400m (Austria, SE Germany), (temps higher to the NE) Sunday – Colder in most areas, but still a little colder to the North 850Hpa temps -5c to -2c and FL 700m to 1100m (Germany, Liechtenstein, Switzerland, N Austria) 850Hpa temps -1c to +1c and FL 1100m to 1400m (S Austria, Northern Italy) Monday and Tuesday – Similar temps to Sunday, winds now from the North East 850Hpa temps -5c / -6c to -3c and FL 700m to 1000m (S Germany, Liechtenstein, Switzerland, N Austria, France) 850Hpa temps -2c to -1c and FL 1100m to 1300m (S Austria, Northern Italy) Wednesday – A little less cold, winds still from the North East 850Hpa temps -5c to -4c and FL 800m to 1100m (S Germany, Liechtenstein, N Switzerland, Far N Austria, W France Alps) 850Hpa temps -3c to +2c and FL 1200m to 1800m (S Switzerland, most of Austria, Italy, E France Alps) Thursday – A little colder again, winds still from the North East 850Hpa temps -4c to -2c and FL 900m to 1100m (S Germany, Liechtenstein, Northern and Central parts of both Switzerland and Austria, W France Alps) 850Hpa temps -2c to +2c and FL 1100m to 1600m (S Austria, Northern Italy) Friday – Somewhat milder from the west, as a Tropical Maritime airmass approaches 850Hpa temps -2c to +2c and FL 1200m to 1800m (S Germany, Liechtenstein, Austria, Northern Switzerland, NE Italy) (coldest over Austria) 850Hpa temps +2c to +7c and FL 1800m to 2200m (S Switzerland, French Alps, N and NW Italy) Precipitation Weekend Heavy precipitation moving Eastwards across the Alps during Saturday, with the heaviest of the precipitation towards the south of the Alps. Snow level never above 1200m, and dropping to around 600m by Sunday morning. Further precipitation on Sunday, more especially for eastern areas, Snow levels riding to 800m (North) 1000m in (south) midday dropping back to circa 400m-600m by evening. Monday and Tuesday Further precipitation continuing through much of Monday and Tuesday for the Alps, with snow levels never above 1000m, and closer to 500-600m overnight. Wednesday to Friday Turning a bit drier fro a time midweek, with precipitation edging in from the west on Friday, with snow to 1600m-1800m. Snow amounts Charts from snow-forecast.com Quite widely over 50cm for Southern parts of the Alps over the next 72 hours above 1500m, with 75cm-1m in some parts, with up to 75cm, possible above 1000m. A further 25-50cm possible over parts of the Alps for the following 3 days, this time with Central areas receiving more. Less snow expected to North Eastern areas, with 10-20cm more likely here this week. Summary Another snowy start for the Alps this week, with snow to quite low levels, drier for a time midweek, before perhaps a little milder towards next weekend.
  7. Current Synoptics and Conditions Rather mixed over the Alps in recent weeks some heavy snow at altitude but with temperatures never being that cold, some lower resorts seeing more in the way of rain than snow. Synoptics Ongoing This general theme continuing into next week, with winds generally from a westerly direction. It is unlikely to be very cold apart from a transient North Westerly flow and Polar Maritime airmass midweek.The flow also South Westerly at times, however no sign of the ridiculously mild air we have seen at times recently.This combined with generally unsettled weather means that there could be a lot of snow again for the higher resorts and slopes, as ever though the detail makes all the difference. Charts - Sunday to Tuesday Charts - Wednesday to Friday Sunday – Turning colder from the west 850Hpa temps -2c to +2c and FL 1200m to 1600m (France, W Switzerland, Italy and S Austria) 850Hpa temps +4c to +7c and FL 1800m to 2400m (Germany, N and NE Austria) Monday – Westerly winds 850Hpa temps +1c to +4c generally, locally +5 to +6c Switzerland/ Austria border FL 1800m to 2200m generally Tuesday – South Westerly winds, cooler in the South 850Hpa temps 0c to +3c and FL 1600m to 2000m (Italy and Southern parts of both Switzerland and Austria) 850Hpa temps +4c to +7c and FL 1800m to 2400m (Germany, N and NE Austria) Wednesday – North Westerly winds, much colder from the North for all areas 850Hpa temps -6c to -3c and FL 800m to 1000m generally 850Hpa temps -3c to -1c and FL 900m to 1200m (Italy and far South of Austria and Switzerland) Thursday – South Westerly winds return, milder from the SW 850Hpa temps -3c to -1c and FL 1000m to 1400m generally 850Hpa temps 0c to +2c and FL 1400m to 1800m (France and W Switzerland) Friday – South Westerly winds return, milder from the SW 850Hpa temps 0c to +4c and FL 1200m to 1800m generally Total Precipitation There are too many potential snowfall events to try to go into detail this week with pretty much every day there are bands of precipitation edging in from the west. While Western areas are likely to see the bulk of the precipitation, most of these events are likely to push across further east, so most areas of the Alps are likely to see large precipitation totals this week, perhaps only the NE of Austria remaining relatively drier. The GFS 06Hz run suggests precipitation totals of up to 6 inches for France and W Switzerland, 2-4 inches E Switzerland, SW Germany and W Austria and 1-2 inches SE Germany, and Central Austria. NE Austria seems likely to be drier with only 10mm expected here, while N Italy looks likely to see 4-6 inches of precipitation. Total Snowfall The big question is how much of this will be snow, snow Estimates this week. Above 2000m it looks as if it will be an all snow event, Snow Totals 1m+ (west) up to 50cm-1m Central areas. 1500m-2000m looks like the vast majority will be snow, and all snow from Midweek onwards Snow Totals 1m+ (west) up to 50cm-75cm Central areas, 1250m-1500m Rain/Snow mix this weekend, Snow midweek, then more Snow than rain Thursday/Friday Snow Totals 20cm-50cm (west) up to 50cm Central areas, 1000m-1250m Rain to start, Snow midweek, then a rain/snow mix thereafter 750m-1000m Rain to start and finish, mostly snow midweek (From snow-forecast.com) Precipitation Charts Summary A very unsettled and snowy week for the higher Alps. Probably not the best skiing conditions at times due to the heavy snowfalls, but this should help the ski season going forward.
  8. Current Synoptics and Conditions Some very mild weather over the Alps over recent days with South Westerly winds. However due to the previous heavy snow, still some very good conditions, although lower slopes were starting to suffer with thinning snow depths. Synoptics Ongoing Weekend Mild South Westerly winds continuing to bring mild and settled weather over the Alps for Saturday morning and early afternoon. However a cold front is set to edge in from the north West later Saturday and into Sunday. This will bring colder weather from the North West and heavy precipitation over much of the Alps for Sunday, more details on the expected snow level in the detailed section below. However turning a bit milder from the South West later in the day. Monday and Tuesday Very mild South Westerly winds and High Pressure edging into the Alps for Monday and Tuesday, and any precipitation in the east quickly edging away, Freezing levels may reach 4000m for South Western parts of the Alps, but turning a little cooler from the North West later on Tuesday. End of Week Continuing to turn much colder over the Alps with a Polar Maritime airmass affecting all areas by Thursday, and with fronts edging in bringing a snow risk across the Alps. There are also signs of a further North Westerly outbreaks over the Alps into the weekend. Alps Temperatures Saturday - Sunday Mild to start, turning colder from the North West late Saturday into Sunday, before turning mild again from the South West later Sunday. Saturday 850Hpa temps +0c to +4c and FL 1800m to 2200m (Generally) Sunday 850Hpa temps -4c to +2c and FL 900m to 1800m (Austria, colder in the east) 850Hpa temps +0c to +4c and FL 1800m to 2600m (France, Switzerland and Western Alps, milder to the SW) Monday – Tuesday Turning much milder for Monday and to start Tuesday, turning a bit colder from the NW later into Tuesday evening. Monday 850Hpa temps +4c to +11c and FL 3000m to 4000m (France, Switzerland and Western Alps, milder to the SW) Tuesday 850Hpa temps +4c to +7c generally and FL 3000m to 3200m Wednesday - Friday Colder again from the North West, but slightly milder again from the west on Friday Wednesday 850Hpa temps -2c to +3c and FL 1200m to 2200m (colder North and West, milder to the South and Italy) Thursday 850Hpa temps -4c to -7c and FL 600m to 1000m, perhaps locally 1200m in the south (colder North and West, milder to the South and Italy) Friday 850Hpa temps -1c to +2c and FL 1200m to 1800m (France, Switzerland and Germany) 850Hpa temps -2c to -7c and FL 600m to 1400m (Austria, coldest further east) Total Precipitation There appear to be two main areas of precipitation this week. A cold front is set to edge in from the North West later on Saturday across much of the Alps, and is set to remain over the much of the Alps on Sunday, before clearing Austria to the East early Monday. Snow levels to start around 1200m to 1500m Saturday midnight, dropping to 1000m to 1200m by 6am Sunday, however increasingly steadily to around 2000m by midday Sunday for France, Switzerland and other Western areas, and this spreading into Austria later. Snow amounts possible (est) at 1000m 0cm (rain event) 1500m 20cm (rain later) 2000m 50cm (perhaps rain later in west) 2500m 50cm-75cm Then drier until midweek before another front edges down from the North West around Wednesday, looking light to start but intensifying as it edges south. With the snow level 1400m on its leading edge, 1000m behind the front. This is forecast to drop steadily through the event to 800m by midnight and to 600-800m during Thursday so a much better event for lower slopes and resorts than the one over the weekend. Snow amounts possible (est) at 1000m 15cm (rain to start) 1500m 20cm (snow preceded by rain) 2000m 30cm 2500m 40cm Summary A complete mixed bag this week, Some snow at times for all, but also some rain for most late Sunday, Very mild indeed Monday and Tuesday. Then colder from the North West with the forecast of snow for many, and looking cool, with the chance of further NW outbreaks into next weekend and quite possibly beyond.
  9. Current Synoptics and Conditions After heavy snowfalls a few weeks and recent drier but very cold weather, skiing conditions remain very good. Settled conditions over the weekend should mean great skiing weather, but starting to turn milder again from the west. Synoptics Ongoing After models divergence in recent weeks, this week weather ifs much easier to forecast, however this does mean that conditions are set to turn very much milder from the West. In many ways this is a trade off, very good conditions to ski in, albeit with softening conditions in the afternoon. This is not good for long term snow retention, as ever higher slopes will be less affected for both. Weekend High Pressure building over NW Europe, with milder weather starting to spread in from the west, with a warm front bringing some precipitation across the Alps on Saturday. Very mild over the Western Alps by Sunday, staying much colder over Eastern Austria for most of Sunday, however turning more settled on Sunday. Monday and Tuesday South Westerly winds spreading across all of the Alps by the end of Tuesday, with very mild and settled weather across all of the Alps by the end of Tuesday. End of Week The pattern remains model unchanged, with south westerly winds and largely settled and mild conditions across the Alps, however perhaps cooler weather from the North West at times. Alps Temperatures Saturday - Sunday For Saturday High Pressure centred to the North West Europe, with NE winds, but with the air originating from the SW increasingly over the weekend. 850Hpa temps +2c to -3c and FL Sea level to 600m (Eastern Austria) 850Hpa temps +2c to +3c and FL 1800m to 2100m (SW Alps) For Sunday, turning milder from the west. 850Hpa temps +2c to -3c and FL 900m to 2100m (Western Austria to Eastern Austria) 850Hpa temps +2c to +6c and FL 2100m to 2400m (France, Switzerland and Western Alps) Monday – Wednesday Continuing to turn milder from the West, but settled conditions, with plenty of sunshine. Monday 850Hpa temps +2c to +5c and FL 1800m to 2400m (Western Austria to Eastern Austria) 850Hpa temps +5c to +8c and FL 2700m to 3000m (France, Switzerland and Western Alps) Tuesday 850Hpa temps +5c to +9c and FL 2600m to 3200m (colder Eastern Austria, mildest Western Alps) Wednesday 850Hpa temps +5c to +8c and FL 2400m to 3000m (colder Eastern Austria, mildest Western Alps) Thursday to Friday Perhaps turning slightly colder from the North on Thursday, perhaps a bit milder again from the east Friday. 850Hpa temps +4c to +7c and FL 2300m to 2700m (colder Germany , mildest Italy) Friday 850Hpa temps +0c to +4c and FL 1600m to 2400m (Austria, coldest further east) 850Hpa temps +3c to +4c and FL 2000m to 2600m (France, Switzerland and Germany) Total Precipitation On Saturday, a front edges in from the west, bringing moderate precipitation in places, Snow levels around 1200m in Central/Western areas, well below 1000m in Austria, by the evening. Thereafter, mostly dry this week, but perhaps some patchy precipitation in parts of Austria at times. Summary Turning much milder from the west, however always that little bit colder in Austria, especially Eastern Austria. A better week for skiing in, than for the slopes themselves.
  10. Current Synoptics and Conditions Recent weeks has seen the Alps transformed with heavy snowfalls down to resort level, with superb on piste skiing conditions generally. However there is the concern of avalanches off piste, as shown by the tragic events the past week. This weekend temperature is set to remain very cold giving very good conditions over the Alps. Synoptics Ongoing Very much a classic battleground situation this week. Whenever cold air gets over Western parts of Europe, the Atlantic tries to fight back and re-establish control back over the weather. Usually the Atlantic eventually wins out, but it is seldom easy and often the blocks holds on longer than anticipated. So the detail for this week is very uncertain. Weekend High Pressure centred over North France with bitterly cold North Easterly winds over the Alps. Monday and Tuesday Signs of less cold air trying to edge in from the west, so a east west split, warmest in the west, coldest in the east. End of Week The battleground continues between the “mild” weather to the west, and colder air to the east. Where exactly the dividing line will be is very difficult to pinpoint on a daily basis. Current indications are that it will be less cold in western areas, but remaining very cold over much of Austria. Alps Temperatures and Rainfall (Snowfall) Saturday - Sunday For Saturday High Pressure centred to the North West of the Alps, with NE winds for all. 850Hpa temps -3c (W Italy) to -10c (NE Austria), and -6c to -8c over the majority of the Alps. FL 200m ((NE Austria), to 700m (generally) and 1000m (W Italy) For Sunday a bit colder form the North East. 850Hpa temps -6c (W Italy) to -11c (S Germany, N Austria), FL Sea Level (Northern Alps) to 400m (generally) and 700m (W Italy) The dividing line between the cold and mild very difficult to pinpoint. Monday – Tuesday The dividing line between the cold and mild very difficult to pinpoint. For Monday, remaining very cold in the North and East. 850Hpa temps -9c to -13c (SE Germany, Austria, E Italy), FL 0m to 400m. A bit milder further west, 850Hpa temps -2c to -7c (FL 200m-500m most of Switzerland up to 1000m far SW Switzerland into parts of the French Alps. For Tuesday a bit milder generally from the west. however remaining very cold in the far North and East. 850Hpa temps -7c to -10c (E Austria, NE Italy), FL 0m to 400m. A bit milder further west, 850Hpa temps +1c (far SW) to -4c W Austria (FL 800m-1000m generally and up to 1400-1600m far SW Switzerland into parts of the French Alps. Wednesday - Friday For Wednesday and Thursday Current suggestions are that the milder air to the west, now covering all but the far NE of Austria. 850Hpa temps +2c (SW) to -4 (NE) and -7c (Far NE) FL 800m (NE) [Sea level Far NE] and 1000m-1600m generally across the Alps. For Friday, perhaps a little colder for central and Eastern areas from the east. E Austria, 850HPa -5c to -8c FL 0m to 600m Elsewhere +2 c far SW to -2c, FL 800m (E) to 1600m Far SW Total Precipitation Less precipitation this week generally than recent weeks. However for this weekend there will be moderate snow at times for parts of Switzerland, and Austria (especially Western Austria), which could give a further sizeable top-up over the weekend. Into next week, generally drier but with fronts trying to advance from the west at times, brining some precipitation a times, with the snow level difficult to pinpoint. There may also be some snow at times from Austria which has not been highlighted on the models. Summary Very cold to start, then trying to turn milder from the west, a nightmare to pinpoint, always looking colder in the east. However given the current conditions over the Alps and the lack of any really mild weather on the cards, skiing should remain very good generally for next week.
  11. Current Synoptics and Conditions There has been a change to the conditions over the alps over the past week or so, with colder and snowier conditions becoming more prevalent, more especially over higher slopes. There has been further snow this week, at times to lower levels. However as can be seen when looking at the synoptic chart, winds have returned to a South Westerly direction, so some of the snow has thawed at lower levels. There is also an avalanche at some slopes so be careful off piste. Synoptics Ongoing Weekend The South Westerly wind continues, with low pressure in charge, so this is likely to give some rain, heavy in places, with the snow restricted to higher slopes. Monday and Tuesday The wind direction changes to more of a Westerly then North Westerly flow, bringing in some colder air from the North west, together with Unsettled conditions remaining in charge, there is the risk of further heavy snowfalls, and to lower levels. End of Week There remains a lot of uncertainty as the weather at the end of the week, but looking on the cold side, with further snow at times, perhaps with the risk of much colder from the north edging in by Friday, but this i very uncertain. Alps Temperatures and Rainfall Weekend For Saturday, a fairly mild South Westerly flow across the Alps, mildest in the far SW, colder in the NE. 850Hpa temps generally +3c to +5c, FL 1800m to 2100m generally, however for the far NE closer to 500m with 850hpa values Moderate precipitation initially for the west of the Alps, but spreading across the east later in the day, Snow levels (always approximate) initially 1800m, dropping to 1600m by evening, and closer to 1100m by midnight . For Sunday SW winds again, but starting to turn a little colder to the North west of the Alps. 850Hpa temps generally +3c to +5c, FL 1600m to 2000m generally. Precipitation to start in Austria, but clearing early afternoon, however more precipitation edges in from the west becoming heavy over SW Germany and parts of Switzerland by evening. Snow levels generally 1200-1500m. Monday - Tuesday For Monday Low Pressure over the Alps, with conditions set to turning colder for the far NW, but briefly milder for times further South and East, with a mild sector, but much colder here by evening. 850Hpa temps +1c to +3c, FL 1400m to 1600m for parts of France, NW Switzerland, SW Germany, far North of Austria. 850Hpa temps +3c to +6c, FL 1800m to 2200m elsewhere for a time, but much colder by evening with FL similar to NW areas. Heavy precipitation to start in the west, this becoming more widespread as the day progresses across much of the Alps, drier into the evening further west, but continuing over Austria into the early hours. Snow level 1400m in the NW to start, 2000m ahead of the rain band, however dropping steadily from the NW to reach 1200m by evening and 1000m by midnight. With the chance of 20cm of snow generally, and 50cm in some spots to the west, perhaps more in places. For Tuesday, cooler generally with West to North West winds 850Hpa temps -2c to 0c, FL 1100m to 1300m for parts of France, Switzerland, SW Germany 850Hpa temps 0c to +2c, FL 1300m to 1600m for SE Germany, Italy and Austria. Any overnight sleet/snow clearing Austria during the morning, before more precipitation is set to edge in from the west, however this time this is set to be focussed on France, Switzerland and Southern Germany during the day, before extending across into Western Austria by evening. FL lower then Monday, 1000m daytime, dropping back to 400m-600m by evening. Further heavy snow totals are possible with 50cm locally, but less widespread than on Monday. Wednesday - Friday There is a large deal of inter run variation at the moment, comparing the charts below with their 00Hz run (GFS) variation) and the picture looks much different. However my best guesstimate at the moment is for 850Hpa temps to be below zero, and FL in the range 1000m to 1500m across the Alps. perhaps always that little bit colder further north. For Friday there is the risk of turning much colder with sub -5c 850hpa air edging in from the north, and FL maybe as low as 500m, but a lot can change between now and then. In terms of precipitation for these days, the current theme is for precipitation for the north of the Alps Wednesday, to about 1000m, more general precipitation Thursday spreading again from the west, but with potentially high freezing level, but turning much colder Friday, with widespread light to moderate snow. Total Rainfall A lot of precipitation is possible across the Alps, the big question this week is the Freezing Level. With over 1m of snow possible if this came off. Summary A cool week to come for the Alps, very unsettled with the potential for some large snowfalls, there is the chance of over 1m falling in some higher resorts, say above 1800-2000m. The further sown the mountain, the higher the risk that there will be rain instead of snow, at 1500m, it should be mostly snow after this weekend, so possibly 50cm at 1500m. Below 1000m there are risk that there may be more rain than snow, so conditions very uncertain.
  12. Current Synoptics and Conditions Firstly a comparison of where we are now, compared to what was suggested in previous blogs. The synoptic pattern is generally very similar to what was suggested on Tuesday, however more of the Alps has a feed from the SW as opposed to the South East. There has been a snow topup in parts of the Western Alps, but not to the extent forecast on Tuesday. Synoptics Ongoing A bit of a change in the weather pattern in the upcoming week. Initially continuing dry and settled with a Tropical Maritime airmass. However gradually over the weekend, the airmass changes to more of a Returning Polar Maritime airmass, bringing cooler and rather unsettled conditions. This combination of colder and unsettled weather does considerably increase the chance of some much needed snow over the Alps. However winds will still be from the South West, so some lower resorts will see rain as opposed to snow, detail on this will always be tricky to nail. Weekend Monday - Wednesday By now the cooler unsettled conditions are in place, so possibly a snowy period of weather, more especially for the higher slopes (as ever). Thursday and Friday The general pattern is still the same, but perhaps a little bit milder, and some uncertainty this far out. Alps Temperatures and Rainfall Weekend For Saturday a split in the weather, for most of the Alps, W to SW winds, 850Hpa temps +2c to +5c, FL 1200m to 1500m generally, however for the S Germany, NE Switzerland and NW Austria border area 2100m However much colder in Eastern Austria with S to SE winds -7c (SE) to +0c (Central Austria), FL 0m (NE Austria) to 600m (Central Austria) For Sunday SW winds again for France, Switzerland and western parts of both Germany and Italy. 850Hpa temps -3c (N and E) to +2c (South West) , FL 1200m to 1600m generally While SE winds for Austria and Eastern parts of both Germany and Italy 850Hpa temps -9c (N and E) to +3c (South West) , FL Sea level over much of Eastern Austria to 1600m further west. Heavy precipitation for France and Western Switzerland to start the day, this push east during the afternoon and evening to cover Switzerland fringing other areas later, this continuing to edge east into Austria for Sunday but decaying as it does so. Snow levels 1800m approx to start, steadily dropping down to 1000m during the afternoon and evening, staying around 1000m on Sunday. Monday - Wednesday For Monday again a split in the weather, for most of the Alps, W to SW winds, 850Hpa temps +0c to +3c, FL 1200m to 1500m generally However remaining much colder in the far East of Austria with S to SE winds -5c (NE) to -1c (Central Austria), FL 0m (NE Austria) to 900m (Central Austria) to 1500m (Western Austria) A similar pattern on Tuesday, but slightly milder for Eastern Austria. For Wednesday the west to south west flow is set to becoming established across the Alps with 850Hpa temps -1c to +1c, FL 1000m to 1400m generally In terms of precipitation, another front pushing in for early Monday, giving heavy precipitation for Western areas, moving east slowly through the day to effect Austria later, the heaviest of the precipitation always for western areas, with snow generally above 1300m, but at lower levels to around 1000m at times. Thursday and Friday Towards the end of the week, the Alps looks like being on the edge of the cold/mild divide, so apart from it perhaps turning milder at least some of the time, with 850HPa temps well above zero, very difficult to give much detail at this stage. At this stage further areas of precipitation seems likely, again the heaviest most likely to be over western parts of the Alps, perhaps not making it to Austria. the Snow level is a bit more difficult to pinpoint, but Mostly snow above 1800m, and to much lower levels at times. Precipitation This shows that there is a risk of 100mm of rain equivalent over France and W Switzerland, 50-100mm for E Switzerland, 25-50mm for W Austria, and 5-25mm for E Austria. If this was all snow this would give, up to 1m of snow over France and W Switzerland, 50cm-1m for E Switzerland, 25-50cm for W Austria, and 5-25cm for E Austria. However these often tend to overstate precipitation amounts. Summary So in summary a change to the weather pattern for the Alps, heavy snowfalls are expected for higher parts of the Alps say over 1800m, moderate snowfalls are expected above around 1500m while areas above 1200m are more likely to see a mix of rain, sleet and snow. Western areas are likely to see the heaviest precipitation, but conversely drier further east, but any precipitation is likely to fall as snow to lower levels to that further west.
  13. Current Synoptics and Conditions Very much a case of deja vu for much of the Alps, mild and settled with SW winds. However high pressure over Eastern Europe is feeding in very cold air for the far east of Austria. Ongoing Synoptics At the time of the last blog, I was discussing whether the colder weather forecast for Scandinavia would edge South Eastwards towards the Alps. It now looks like this will largely miss the Alps, with the coldest air only impacting the far east of Austria. Further west though it will turn colder with 850Hpa temps falling below zero, and some fronts are set to being a little snow to reasonable levels. Alps Temperatures and Rainfall Wednesday- Largely dry across the Alps once again. For France, Switzerland For the western half of Austria, mild with west to South west winds. 850Hpa temps +2c to +5c, FL 2100m to 2700m Much Colder in E Austria with SE winds. 850Hpa temps -7c (SE) to +0c (Central Austria), FL 200m (SE Austria) to 900m (Central Austria) Thursday - SE winds for more of the Alps, but the coldest air always for the SE, but turning less mild generally. For France, Switzerland For the western half of Austria. 850Hpa temps +2c to +4c, FL 1800m to 2200m Precipitation edging in slowly from the NW, this effecting the far NW for the afternoon and more generally across France and Switzerland by late evening. Snow levels dropping from 1800m down to 1200-1400m later in the day. Perhaps up to 20cm of snow in places. Much Colder in E Austria with SE winds. 850Hpa temps -7c (SE) to +1c (Central Austria), FL 0m (E Austria) to 800m (Central Austria) Friday - Winds E to SE generally across the Alps, but the coldest air always for the SE, but continuing to turn a little colder turning generally. The overnight precipitation continuing to edge east across the Alps, tuning much drier for France and Switzerland, with the heaviest precipitation for Austria during the late morning and afternoon tuning drier into the evening. Snow levels dropping from 1200m down to 600-800m later in the day and to sea level in the far East. Perhaps up to 10-15cm of snow in places. 850Hpa temps generally -2c to -5c, always colder to the east but perhaps +3c in far SW. FL at sea level far east of Austria 1200m-1500m generally elsewhere, but 1800m far SW. Precipitation These charts show the precipitation moving wet to east, starting midnight into Thursday and lasting until Friday evening. Summary Turning a little colder with some fresh snow across the Alps, perhaps with up to 20cm in places, not enough to transform conditions, but it should help. Also with colder conditions, it should make snow making equipment more effective. Outlook Staying a bit colder into the weekend, with 850Hpa temps below zero, however perhaps turning much colder from the East. Detail is uncertain, but further precipitation is possible over the weekend into next week.
  14. Current Synoptics and Conditions The current pattern over the Alps has seen some very mild and largely settled weather. Very good for getting out and about, but not any good at all for "natural" snow conditions. However, with clear conditions, even under this mild airmass, temperatures drop sharply overnight, meaning that snow cannons can be used. As a result, on piste conditions are reasonable, but off-piste remains very poor for the time of year. Looking at the pattern for today, compared to what was forecast last week, these are very similar, the only difference is that the pattern is slightly further east, but not by enough to change the Alps weather. Ongoing Synoptics Initially the theme seems very similar with High pressure over Mainland Europe with winds continuing to be from the South West and bringing in a very mild Tropical Maritime air mass. However there are changes much colder air from the Arctic is set to sweep into Scandinavia from Saturday (26th). Into the start of next week, High Pressure then builds over Northern Europe, with NE winds set to flood this colder air towards the Alps. However there are still model variations, some have the colder air remaining further east, and others have 850Hpa temps of below -10c by Next Thursday. Alps Temperatures and Rainfall Friday - Christmas Day - Mild, dry with lots of sunshine with SW winds, 850Hpa temps +3c (NE) to +8c (SW), FL 2300m (NE) to 2900m (SW) Saturday - Mild, dry with lots of sunshine with SW winds, 850Hpa temps +3c (NE) to +10c (SW), FL 2400m (NE) to 3400m (SW) Sunday - Mild, dry with lots of sunshine with SW winds, 850Hpa temps +7c (NE) to +10c (SW), FL 2800m to 3100m (Generally) Monday - Mild, dry with lots of sunshine with SW winds, 850Hpa temps +6c (NE) to +9c (SW), FL 2800m to 3100m (Generally) Up until this point, a fairly straightforward forecast, with very high levels of certainty - thereafter things get a bit more uncertain. Tuesday - For the western half of the Alps. mild with west to South west winds, Frontal precipitation is set to move east for the far west of the Alps, the Snow Level around 1800m by day, dropping back to around 1200m in the evening. Perhaps much colder further east with northerly winds. 850Hpa temps -3c (SE) to +5c (N), FL 900m (SE Austria) to 2400m (NW) Wednesday and Thursday - A very large amount of uncertainty - However current models, are suggesting that 850HPa temps could go down to -15c in E Austria, with a FL at sea level, staying a bit milder in parts of the SW , with 850Hpa of up to +3c and FL of 1800m. Outlook - There are big doubts as to what will happen for the later part of next week, however this is the first time in a while, that there have been some decent prospects for improving conditions, the next update will be early next week, and by then hopefully we will have a better idea as to whether these colder synoptics were a blip or a trend. Hints as well of some snow later next week.
  15. Current Synoptics and Alps Weather Summary The mild weather continues to effect the Alps with conditions and temperatures better reflecting early Spring than Early Winter. The use of snow cannons has meant that many piste runs are open, especially at higher levels, however a quick glance at webcams will show that off piste conditions are a different story, either closed or showing pastures of green. Comparing the forecast for last week to today's synoptics. While the pattern for the Alps is largely the same, mild and largely with SW winds, the upstream pattern is a little different with the flattening of the jet not really happening, with the SW flow largely continuing. This Weeks Synoptics For the next week the weather pattern looks largely similar, the wind direction tend to fluctuate from SSW winds to SW but always very mild and largely settled. Towards next weekend, perhaps signs of the High pressure over Europe briefly edging eastwards, perhaps allowing more in the way of frontal system to edge in from the west, but this is still a long way off. Alps Temperatures and Rainfall This week I have changed this to include 850Hpa Temps and Freezing Levels. The basic precipitation pattern is that it remains largely dry throughout. Saturday - A South westerly flow and Very mild in the west, 850Hpa temps of 10c (FL 3200m), cooler for the time in the NE 850Hpa temps of 3c (FL 2400m) Sunday - A South westerly flow and Very mild across the whole Alps, FL levels 3000-3300m, 850HPa up to +11c in Southern Germany, closer to +4c in SE Switzerland and SW Austria. Monday - The winds veering westerly over the Alps, so a little less mild, 850HPa temps +4c to +7c, and FL 2400m-2700m, cooler in the North, warmer in the south. Tuesday - The winds reverting back to South Westerly and turning very mild, 850HPa temps +5c to +9c, and FL 3000m (Eastern Austria) to 3600m (Western Alps). Wednesday - The winds remaining South Westerly with the mildest of the weather moving away to the East, 850HPa temps +7c to +9c, and FL 2900m (Western Alps) to 3600m (Eastern Austria). Thursday - The winds remaining South Westerly, 850HPa temps +4c to +7c, and FL 2500m to 2700m. Friday - The winds remaining South Westerly, but originating from the South East for the SE Alps. 850 HPa Temps 2c over Northern Italy (FL 2300m), up to +9c for Southern Germany, (FL 3000m) Below are the precipitation charts for Thursday and Friday, the Thursday shows the heaviest precipitation for the Alps for the week, and it is still mostly dry. While the Friday charts shows that a dry Christmas Day is likely favoured. The total precipitation charts also indicate a dry week for the Alps. Summary A dry and very mild week in the Alps with very little snowfall expected, there is more of a chance of some snowfall for the post Christmas weekend, but the week after, still looking on the mild and mostly dry side.
  16. Current Synoptics and Alps Weather Summary Last week was a largely mild one across the Alps with mild South South westerly winds within a tropical Maritime air mass If we look at today's chart (left) and compare to the forecast charts from the last blog (right) we can see the general weather pattern is very similar, however the low pressure is slightly further to the west, however the High pressure is very much still dominant over mainland Europe, and if anything stronger than previously forecasted. Upcoming Synoptics It is very much a case of deja vu for the Alps synoptics this coming week. Winds generally come from the West to South West. Which means it largely remaining on the mild side. There is a time around the middle of the week, though that there is a chance of some colder weather snipping for far East of Austria. Freezing Level and Precipitation Saturday - Mild and dry for SW Alps with Freezing Level (FL) at 3000m, cooler as you move further North and East, with the chance of moderate precipitation for a few hours over NE Austria, snow above around 1400m. Sunday - A mostly dry day, perhaps a little evening precipitation for the far NE of Austria with the FL across the Alps in a narrow range between 2000m to 2400m. Monday - Another mostly dry day, with the milder air being mixed out, with FL slightly lower at around 1800m-2200m. Tuesday - Dry over Southern parts of the Alps, with some precipitation moving East over southern Germany into Austria later in the day. Milder in the west FL at 2200m , closer to 1800m over Eastern Austria. Wednesday -There will be spells of precipitation for much of the North and west of the Alps overnight and for the morning, this becoming confined to Southern Germany and Switzerland and the far west of Austria by afternoon and heavy and prolonged in places. this spreading east during the evening, to reach Western Austria by midnight. Heavy snowfall perhaps 20cm possible above around 2000m. Milder in the west FL at 2600m, Switzerland 2200-2600m, Western Austria 1800m-2200m, as low as 1400m far Eastern Austria. Thursday - Overnight precipitation is expected to continue over Western Austria until morning, before moving to central Austria for the afternoon, and Eastern Austria by evening Heavy snowfall perhaps 20cm possible above around 2000m, the heaviest snowfall at the moment likely for Western Austria. Milder in the west FL at 3000m, Switzerland 2200-3000m, Western Austria 2100m-2400m, as low as 1200m in extreme NE corner of Austria. Friday - A mostly dry day, milder generally across the Alps with the FL across the Alps in a narrow range between 2000m to 2400m. Overall Precipitation Mostly Dry for Southern Europe, perhaps up to 50mm of precipitation for Eastern Switzerland, Western Austria and Central Southern Germany with large snowfalls for the higher slopes. Summary and Further Outlook Mostly mild and dry this week, however a chance of moderate snowfall for the higher resorts in the Central alps around midweek. Looking further ahead into the 7-14 day range, initial indications are staying Generally mild however a chance of some northerly incursions before Christmas.
  17. [b]Summary[/b] There was some good snowfall over parts of the Alps last weekend with some parts of Northern Italy seeing 1m of snow. However it was not quite as extensive as forecast with parts of Switzerland, not doing as well as expected. Generally though there are good conditions over the Alps albeit with the recent sunny and warm weather in the afternoon, giving some afternoon spring snow conditions. [b]Synoptics[/b] [size=3][font=arial]Currently over the Alps there are South Westerly winds and High Pressure however this pattern is set to change overnight and into Saturday.

By no means the coldest week in the Alps, not the snowiest but most areas are likely to see some fresh snow this week, even if at times, some of the precipitation will be of rain at lower slopes levels. All in all not a bad skiing week for late winter.

  19. [size=4][font=arial][b]Summary[/b][/font][/size] The last 24-48hours has seen some very good snowfall for the Alps, more especially towards the NW, this is set to continue overnight into Saturday. The weekend starts on a cold unsettled them with winds from North Westerly direction. This is associated with low pressure off the south coast of Scandinavia. This rather unsettled and cold theme continues through the weekend. [attachment=242964:Alps 30 Jan.JPG] [attachment=242965:Alps 30 Jan + 24.JPG] The following is of quite high uncertainty On Monday a small low pressure system pushes in from the North West and slowly edges across the Alps turning things briefly less cold. However turning back colder by Wednesday and colder again by [attachment=242966:Alps 30 Jan + 48 b.JPG] [attachment=242967:Alps 30 Jan+ 72.JPG] Wednesday, as it exits to the east and reintroduces colder North East winds.

[b]Precipitation [/b] Saturday - After overnight snow moves away from the NW, Patchy precipitation (snow to resort level) will continue in Austria for a time before dying away, another front edging in from the NW for the evening again heavy in places. Sunday - Snow from the NW continuing in the morning turning patchier later and moving east. Monday - Further showery snow for the Northern half of the Alps, however turning drier later Tuesday - Heavy precipitation over central Italy, trying to edge north into the Italian Alps for the evening and early overnight period. Wednesday - Overnight precipitation edging NE into many parts of Austria and Switzerland snow to resort level in the north, snow over 1000m for Italy and SW Austria. Rest of week - After the front dies way, showery precipitation likely over the Alps, largely of snow.

  20. [b]Summary[/b] A mixed picture over the Alps, rather unsettled but with some snow over higher slopes and resorts and some heavy falls in places as well. [url="http://www.snow-forecast.com/pages/tips_full"]http://www.snow-fore...pages/tips_full[/url] Looking at today's forecast, [attachment=133109:13 Alps today.JPG] We can see a lot of precipitation forecast, with freezing levels forecast to be around 1700-2000m. [b]This week[/b] A slight change in format going forward for the rest of the season with daily summaries containing all the info. [b]Sat 14 April [/b]- Generally unsettled with further precipitation over much of the Alps, freezing level 1400-1800m generally, up to 2100m close to Southern Switzerland/Austria border. The precipitation potential lasting for the full 24 hours of Saturday. Freezing levels early Saturday only slightly lower than daytime levels. [b]Sun 15 April [/b]- Very similar to Saturday, again unsettled with widespread precipitation, heavy in places, freezing levels a bit higher, especially to the east,, 1400m to the NW, but 1800-2200m generally. So over the weekend, snow depths decreasing at lower levels, but accumulating nicely over 1800m or so [b]Mon 16 April [/b]- Another unsettled day in general, turning colder from the north with more of a temperature gradient. FL levels 1000-1200m for Germany, the far north of Austria, Switzerland and 1800m+ for South parts of Austria and Switzerland, and for Italy. The showers not as intense as over the weekend. [attachment=133110:13 Alps +72.JPG] [b]Tue 17 April [/b]- Turning much colder overnight over the northern half of the Alps, some showers again but less than over recent day. Freezing levels recovering a bit by day, close to 1200-1500m north, around 1800m SW Austria, S Switzerland and NW Italy. [b]Wed 18 April -[/b] Very cold overnight to the NE of the Alps, showers continuing over night over central areas, some of these may be heavy, a front is set to push into western parts by morning, and this many merge with the showers, to give a more widespread area of precipitation, Freezing Levels similar to recent days. [attachment=133111:13 Alps + 120.JPG] [b]Thur 19 April and Fri 20 April -[/b] Both days are looking rather unsettled with further outbreaks of precipitation some of which may be heavy. Freezing levels, again around the 1500-2200m area, always highest towards the South and East, and lowest to the west and north. [attachment=133112:Fri 13 Mar +168.JPG] [b]Summary[/b] Altitude always makes a difference across the Alps, but never so much as this week, at lower levels, there will be a lot of rain, milder temps, washing away the snow, higher levels, and over 2000m is likely to see mostly snow, will see large snow accumulations, perhaps as much as 30-50cm in places. However, it will come a no surprise that altitude is needed this late in the season and here the end of the season will be far better than 2011.
  21. [b]Summary[/b] As we move into March, the technical winter period is now over, but the skiing season across the Alps continues into April for many resorts, and depending on the snow conditions, into late April in many resorts. The weather across the Alps has been mild for the most parts with spring skiing conditions, so resorts have been losing their snow cover, and slopes are seeing the snow base thin and turn slushy, however snow levels are still very good after very heavy snowfalls for much of the winter. Less mild than recently over the next week, with some further snowfalls more especially over the higher hills as ever. [b]Synoptic Summary[/b] For the rest of the winter period, the synoptic summary will not as detailed as it was earlier in the season. High Pressure to start the weekend over the Alps and mild. By Monday a North Westerly flow brings Polar Maritime air and cooler conditions to initially the UK and then to the Alps. This is also associated with a small low pressure system, with the potential for moderate snowfalls to fairly low levels over the Alps. [attachment=132084:3 Mar today.JPG] [attachment=132083:3 Mar + 51.JPG] However this cold unsettled period doesn't last that long as Azores High pressure does edge back in as it has does so much this winter, this will reintroduce more settled and milder weather for the Alps by midweek. There is a chance of a brief North Westerly flow again by around Thursday, but this may miss the Alps to the east, but this does lead to some uncertainty before the weekend.

  22. This is the first in a series of blogs looking at the Snow and Skiing conditions for the Alps for winter 2011-12. A cursory look at the webcams across the Alps will show that snow levels are currently on recent at this early stage, and that temps over the Alps have been milder than normal so far in November. As an example the following table shows maximum temps for Zermatt (1600m - Switzerland) and Salzburg (450m - Austria), this only gives a snapshot, but it can be seen that Temps are milder in 2011 than in both 2010 and 2009, and it is unusual that there has been a cold snap recently. [attachment=123366:Winter Temps.JPG] <- Table with temps of Zermatt and Salzburg. Synoptically can this be explained, firstly if we were to look at this years patterns, this gives the 850Hpa temps across Europe and the wind direction. [attachment=123368:GFS 01 Nov.png] [attachment=123369:GFS 02 Nov.png][attachment=123370:GFS 03 Nov.png] [attachment=123371:GFS 04 Nov.png] [attachment=123372:GFS 05 Nov.png] [attachment=123373:GFS 06 Nov.png] [attachment=123374:GFS 07 Nov.png] [attachment=123375:GFS 08 Nov.png] [attachment=123376:GFS 09 Nov.png] [attachment=123377:GFS 10 Nov.png] [attachment=123378:GFS 11 Nov.png] [attachment=123379:GFS 12 Nov.png] At no time is there a wind from any northerly direction for the Alps, and for the majority of the period, 850HPA temps are above +5c, the only exception being for Eastern Austria after the 10th. In Summary, At the start of November, there was a High Pressure over Eastern Europe with low pressure further west, and the Alps in the middle seeing mild Tropical Maritime air with South Westerly winds. By around the 5th-7th, low pressure took over for much of Continental Europe, but with winds remaining from a SW direction bringing 850Hpa temps around +10c for a while. By around the 10th, High Pressure edging back into Eastern Europe with winds edging back to a SE direction, with less mild winds trying to edge in from the South East. If you look at previous years, there has been some colder air at different times across early November. 2010 started mild with a Bartlett style High. [attachment=123380:Nov 4 2010 850Hpa.gif] [attachment=123381:Nov 4 2010.gif] However winds then turned around to a Northerly direction on the 6th, this gave Polar Maritime air which lasted for a few days, giving a general cool down across the Alps. [attachment=123382:Nov 7 2010.gif] [attachment=123383:Nov 8 2010 850Hpa.gif] [attachment=123384:Nov 10 2010 850Hpa.gif] [attachment=123385:Nov 10 2010.gif] [attachment=123386:Matterhorn Nov 2010.jpg] [attachment=123387:Matterhorn Nov 2011.jpg] This gave a topup of snow for November 2010 as opposed to the less snowy picture for 2011, however much of the snow seen on the slope above Zermatt was delivered during the 4th-8th November. 2009 saw more of a pronounced change around over the Alps. again it started mild with a High pressure to the east bringing in southerly winds. However by the 3rd winds had changed round to a NW flow, with associated polar maritime air. It stayed quite cool for a few days, before low pressure brought NE winds and sub zero 850Hpa air. [attachment=123395:Nov 1 2009 850 Hpa.gif] [attachment=123388:Nov 3 2009.gif] [attachment=123389:Nov 6 2009 b.gif] [attachment=123394:Nov 6 2009 850 Hpa.gif] [attachment=123390:Nov 9 2009.gif] [attachment=123393:Nov 9 2009 850 Hpa.gif] [attachment=123391:Nov 12 2009.gif] [attachment=123392:Nov 12 2009 850Hpa.gif] Even though the Alps do not require perfect weather conditions to bring cold weather and snow, indeed 0c at 850HPA will bring snow to most resorts over the Alps. It is just as vulnerable to Bartlett High and Southerly winds as the UK. A look ahead for the rest of November prospects will follow over the next few days, and I will also post a few more webcams to show the difference between this year and previous ones on the ongoing discussion thread here. - > [url="http://forum.netweather.tv/topic/71533-alps-snow-and-weather-conditions-2011-2012"]http://forum.netweat...tions-2011-2012[/url]
